구별 사이 초음파 거리 측정기 및 레이저 거리 측정기
레이저 거리 파인더 is an instrument that uses laser to accurately measure the distance of the target. 언제 the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target.
1. In terms of accuracy, the measurement accuracy of the ultrasonic rangefinder is at the centimeter level, and the measurement accuracy of the laser rangefinder is at the millimeter level;
2. In terms of measurement range, the measurement range of the ultrasonic rangefinder is usually within 80 meters, while the measurement range of the handheld laser rangefinder can reach up to 200 meters, and the measurement range of the laser rangefinder telescope can reach hundreds of kilometers. Even farther away (the measurement accuracy of laser ranging telescopes is usually 1 meter or tens of centimeters).
3. 그 초음파 거리 파인더 is 쉬운 to 보고 오류. 이후 그의 초음파 범위 파인더 방출 소리 파동 및 has 그 부채꼴 방출 특성 의 소리 파동, 언제 거기 많은 장애물 어디서 the 소리 파도 통과, 거기 의지 될 더보기 반사 소리 파도, 더보기 간섭, 및 오류 보고. The laser rangefinder is a very small beam of laser light that is emitted and then returned, so as long as 빔 캔 통과 통과 % 2C 거기 거의 아니오 간섭.
4. The price of an ultrasonic rangefinder ranges from tens of yuan to several hundred yuan, and the price of a laser rangefinder ranges from a few hundred yuan to several thousand or tens of thousands of yuan, depending on the accuracy and distance.
